FS-Curtis ML7.5-SH — 7.5 HP Air Compressor
A shop that's outgrown a 5 HP compressor's output during a busy multi-bay afternoon needs the extra CFM of the 7.5 HP tier without paying for accessories it doesn't need yet.
The FS-Curtis ML7.5-SH is a two-stage reciprocating compressor rated for 7.5 HP with an 80 gallon horizontal ASME tank, built for shops and commercial operations that need compressed air on tap all day without paying for accessories they don’t need.
Who the ML7.5-SH Is Built For
- ✅ A three-bay shop that added a tire machine last year and started noticing the compressor cycling nonstop by Thursday afternoon — the old 5 HP unit just can't keep up anymore, and 28.7 CFM at 7.5 HP is the fix
- ✅ An owner who installed a standalone refrigerated dryer on the shop's main line two years ago and doesn't want to pay for a second one bundled into a new compressor — this base unit skips that cost
- ✅ A shop tucked under a low storage mezzanine where the horizontal tank's lower overall height is the only configuration that physically clears the joists
- ✅ A multi-location operator who's already running three ML Series units at other shops and wants the fourth location on the same parts and service plan, starting at the entry tier to control this year's capital spend
- ✅ A tech who's had to wait on air pressure recovering mid-brake-job more than once this quarter, and the shop owner finally approved the upgrade from a 5 HP unit rather than living with it another season
What the ML7.5-SH Is NOT Built For
- ❌ Shops whose demand is fully covered by a 5 HP unit — the ML5 line saves real money if 19 CFM is enough
- ❌ Shops wanting factory auto-drain/dryer accessories standard — the Ultra Pack (ML7.5-HUP) adds those, this base unit doesn't
- ❌ Shops needing built-in redundancy — this is a simplex (single-pump) unit; look at the ML7.5-D instead
What Makes the ML7.5-SH Different
Commercial 2-Stage Pump
The ML7.5-SH uses a C79, Cast-Iron, Two-Stage pump built for daily, all-day duty cycles — not a hobby-grade single-stage unit that struggles under continuous shop use.
CFM & Pressure Output
Delivers 28.7 CFM @ 175 PSI and holds pressure up to 175 PSI, enough headroom to run impact wrenches, tire equipment, and paint tools without the tank running dry.
Power Requirements
Single or Three-Phase, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
- 7.5 HP daily-duty output
- Lower entry price, no bundled accessories
- Compact horizontal footprint
- Shops fully covered by 5 HP
- Shops needing redundancy
ML7.5-SH vs. FS-Curtis ML7.5-SV (7.5 HP, Vertical tank) — Which Compressor Is Right for Your Shop?
| Decision Point | ML7.5-SH | FS-Curtis ML7.5-SV (7.5 HP, Vertical tank) |
|---|---|---|
| Horsepower / Tank | 7.5 HP / 80 Gal Horizontal | 7.5 HP / 80 Gal Vertical |
| CFM @ 175 PSI | 28.7 CFM | 28.7 CFM |
| Tank orientation | Horizontal — lower overall height | Vertical — smaller floor footprint |
| Best fit | Shops with low ceiling clearance | Shops with tight floor space but taller ceilings |
Choose the ML7.5-SH when ceiling clearance is limited and you want a lower-profile unit. Choose the ML7.5-SV when floor space is the bigger constraint and you have the ceiling height for a vertical tank. Both stay inside Alamo’s catalog — call (844) 480-6059.
